> Read configured tmux commands; accepts no client-supplied executable input. Returned values may contain executable configuration. Expand named tmux format variables for a pane, such as session_name or window_width. Use it for fields nothing else answers; get_pane_info already returns the common ones, and show_option reads configuration rather than live state.

Server behavior and tool contracts may change. Tool availability depends on the server configuration.
